Hi,

I own a SVD1321C5E (Vaio Duo 13) which I am trying to update to Windows 8.1. The installation is failing while checking for compatibility. It says contact vendor for latest BIOS. I then went to the support site to download latest driver.

BIOS Updates - R0151S7   64 bits   5.02 Mb   04/09/2013

When trying to install this, it says I am already on the latest version of BIOS. I have also ensured all pre-requisites mentioned in Sony website below are met.

What else am I missing? Have tried atleast 4 times so far. Please help.

Regards,

Deepu
